A number of my "traditional" media colleagues don't quite understand why I'm choosing to go to Vidcon, the annual gathering of YouTube content creators. As an independent (and traditional) content creator (aka filmmaker), I've come to greatly respect the spirit of the YouTubers that are constantly inventing (and re-inventing) the world of online video.
In my opinion, the best of them (your definition - YouTube is a place where there really is something for everyone) - have several traits in common. Here are my top five:
1. They're Auteurs - they often do everything - write, producer, direct, act AND promote their work.
2. They're not equipment centered - they're content centered.
3. They're showing that grassroots independent co-production is no longer impossible - it's commonplace.
4. Like the earliest pioneers of the motion picture industry, they're often learning - and willing to learn - "on-the-job."
5. They respect, respond and interact with their audience
